Sorry, I do not have a list (although you can see a caiman lizard in this photo). I did a quick search of the Forth Worth forums hoping someone had posted a list, but did not find anything.
As you may or may not know, I recently published a book on zoos of the southwest USA which has a chapter on Fort Worth Zoo. However, I did not bother to list all of the dozens of reptile species on display, as most readers would not be interested in a long list. Here are the ones I mentioned in the chapter:
Mexican tiger rat snake
gharial
saltwater crocodile
caiman lizard
Indochinese serrated turtle
sharp-backed monkey tree frog
Oustalets chameleon
Utila island iguana
green tree monitor
Chinese crocodile lizard
Mexican leaf frog
African bush viper
Surinam toad
Boelens python
Chinese giant salamander
Komodo dragon
